Kuroba Fumiya
Kuroba Fumiya is a member of the Kuroba Family, a branch of the Yotsuba clan. He was once in the running to succeed Maya before that didn't pan out.
He's got an older twin sister, Ayako, and the two of them showed up early on during the Reminiscence Chapter at a formal ball their father Kuroba Mitsugu threw. That's basically where fans first got a glimpse of them.
